5.11 A body constrained to move along the z-axis of a coordinate system is subject to a constant force

\mathbf{F}

given by

\mathbf{F}=\hat{\mathbf{i}}+2 \hat{\mathbf{j}}+3 \hat{\mathbf{k}} \mathrm{~N}

where

\hat{\mathbf{i}}, \hat{\mathbf{j}}, \hat{\mathbf{k}}

are unit vectors along the

x

y

- and

z

-axis of the system respectively. What is the work done by this force in moving the body a distance of 4 m along the

z

-axis?
